Application rled April 2,

"the present inven ii relates to closure operators and has rercrence more particularly to a device for operating 'the Windows or automobile do is ot the closed types oi' vehicles.

@ne oi the importaV objects oi the `present .invention r vide a Window operat device, 'vv rudes a ineens for inaintaining the i indou' pane in any ralsedor lowered posi ion, additional nieans being provided whereby the window pane niay he readily and easily actuated for sliding;` niovenient in the Window ironie.

il further object ot the invention 1s to provide a Window operating` device, which is siniple in Constructioiia strong and durable7 and otherwise Well adapted tor the purpose for which it is designed;

lOther objects and advantages ofthe invention will beconie apparent during 'the course oit' the following detailed description.

in the accompanying drawings, forming a part oi this application andan which like parte are designated ley similar' reference characters throughout the several views:

Figure l is a view partly in section and partly in elevation or 'the vv'indow traine or an autoinoloile door, showing;v the opera-.tuig` means tor raising' and lowering the Window pane, the latter being shown in itsloWered position. p

Figurel 2 is a transverse section 'taken approximately on the line 2 2 ot Figure 1, looking in the direction `ot the arrows.

Figure 3 is a similar section` taken approiriinately on the line 3&3 pi: Figure l.

Figure Ll isa sectional'vlew talren approiriinaftely on the line ll-Ll of Figure l, looking-` in the direction of the arrows, and

Figure 5 is a groupv perspective of the upperend of the lever and the handlevvhich is associated therewith.

ln the drawings, wherein for the purpose ot illustration is shown the preterred enihodiinen't ot niy invention, the numeral l designates the Window traine oil aneutoinoliile door or 'the like and adapted ior ver-- tical slidahle movement Within the upper portion oi 'the traine the Window pane 2. rllie usual guides Yfor the side edges oi the Window traine are to he provided, and as the saine torrns no important partot the present invention, a deal-led description and yshow'- ingl` oi the seine is thought unnecessary.

nient 3, it being understood of course that one side ol' the door adjacent the compartnient 3 is removable, to perinit the installation oi' niy improved Window operating mechanism. fr window sill extends transversely across the Window traine at the intermediate portion thereo'tl and this 'window sill is iornied with a longitudinal slot 5, which extends for the full length thereof, the Window pane slidable. rlhe Window si l is iornied with an additional longitudinal slot 6, adjacent the rear side ot the traine il of the slot extends to the intermediate oi the sill is clearly seen in Figure 3. The inner side edge of the sill is formed With the slot 7 and this slot communicates with the L illustrated in Figure Zl. these slots will hereinafter be inore fully described. l

My improved Window operating device comprises an elongated lever 8 which is' disposed vertically Within the compartment or chainoer 3 and is tulcrunied at its lower end on' thepivot 9. 'lhe upper end ofi this lever terminates at a point adjacent the Window sill and the upper end of this lever is formed with a longitudinally extending1 slot l0. Adapted tor coope 'ation with the upper slotted end ot the tulcrunied leverl`^ is the handle designated by the numeral 1l,

generally, the saine cinnprising` aptiat strip 12, the upper end oi' which isft-Wi'sted, as at' 1,3 and lthe reduced upper end portion 14 is disposed at right angles to the' body portion otthe strip. The {iatstrip 'l2 oi the lian-y dle 1l entends through the vertical slot 6 :tor'nie'd in the sill fl, so that the reduced upper end 'le Will protrude above the upper i'aoe ot the sill, in the manner as shown in Figures l and e.

'Extending laterally trein the body portion l2 ot the handle ll are a pair O' relatively short vertically spaced pins l5, the saine being adapted to entend through the vertical slot ifornied in the upper portion ot the :tulcruined lever 8 and in which slot the pins are slidalo'le vertically.` An elongated pin 16 entends laterally troni the saine side of the body portion adjacent the twisted portion i3 and this pin lo is operable inv the slot 7' 'lor-ined in the inner side edge ot the vvindoiv sill Ar. The purpose of the pin and slot 16 and 7 respectively is to provide a means whereby the handle Will and the forward end' ver tical slot G in the manner as clearly` rlhe purpose ot' slide parallel to the window sill and to coinpensate for such sliding` movement, the pins l5 cooperate with the slot l0. l`he projecting end of the handle provides a means for swinging' the fnlcrnnied lever S' on its pivot S) and this will be presently apparent.

A relatively short arm I7 is lixedly secured at its inner end to the lever 8 at a point adjacent the fulcruin or pivot 9 and as is clearly illustrated in Figure l, this relatively short arm is disposed at substantially right angles to the lever and extends rearwardly therefrom.

An elongated arm i8 is disposed sulii'tantially transversely within the chamber El and is pirated at its free end adjacent the rear side of the frame l as is shown at 19. This elongated arm is disposed at an angle adjacent the fulcruined end of the lever 8 and the forward end of this arm is reduced as illustrated at 20 and arranged within the reduced forward free end of the arm are a series of spaced openings 2l.

A substantially U-shaped clamp 22 .is secured to the lower edge of the window pane 2 at the direct cent-er thereof. Cooperating with this clamp 22 is the vertically extending lifting bar 23. This bar is pivotally secured at its upper end to the clamp as at 24 and the lower end of the lifting bar is pivotally secured to the forward end portion of the pivoted elongated arm 18, as at 25.

My improved window operating device further includes the provision of a link 26 which affords a pivotal connection between the rear end of the short arm 17 secured to the lower fulcrumed end of the lever 8 and the pivoted end of the transversely extending arm 18, in the manner as clearly shown in Figure l.

Also forming a part of the present invenv tion is a eounterbalancing means whereby the movable elements may be held in any adjustable position for maintaining the window pane in the desired raised or lowered position. This counterbalancing means compries a weight 27 which is slidable vertically in a channeled guide 28 provided therefor and this guide extends from the window sill 4c tothe bottom of the frame l adjacent the forward side thereof in the manner as clearly shown in Figure l. A cable 29 is secured at one end to the upper end of the weight 27 and is trained over a pair of pulleys 30 which depend from the window sill 1l, it being understood, of course, that the side of the guide formed with an opening to permit the cable 29 to extend therethrough. The other end of the cable is .secured to the reduced forward end 2O of the pivoted arm 18, by means of a clevis 3l and this clevis cooperates with the spaced openings in permitting the cable to be adjustably secured to the free end of the cross arm 18.

The operation of my improved device may be briefly stated as follows: Wfhen the window pane 2 is in its lower-most position, the handle ll, will be disposed at the rear end of the slot (l in the window sill Ll, and the parts will be in posit-ion in the manner shown in the full lines in `Figure l. In order to raise the window pane the projecting end lll of the handle is pushed forwardly, 'rinsing the fulcruin lever 8 to swing1 on its pivot and due to the manner in which the fulcrunied end of the lever is connected to the pivoted cross arm 1S. the latter will be swung upwardly to the position shown in the dotted lines, and simultaneously the lifting har 23 will also move upwardly in a vertical plane and as a result the window pane will be raised. The parts of the window operatingdevice are maintained in any set position due to the weight 27 and the cable 29 which is secured to the forward end of the cross arni, and the provision of this commer-balancing means will obviate the necessity of having to provide a pawl and ratchet structure in connection with the window sill and fulcrum lever, suoli as is now commonly provided on window operating devices used for raising and lowering the window panes of automobile doors or windows.

The simplicity of my improved device enables the saine to be readily and easily actuated and furthermore will, at all times, be positive and eflicient in its operation. Also the construction of the )resent device will enable the parts to be reac ily assembled and installed without any difficulty and will furthermore be inexpensive.

lVhile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the appended claims. i

llVhat I claim is:

l. In combination with a window frame, a sill extending transversely in the frame, and a window pane slidably mounted in the frame and through the window sill, a window pane operating device comprising a vertical lever fulcrumed at its lower end in the frame below the lower edge of the pane, a transversely extending arm fulcrunied at its rear end in the frame at a point above the fulcrumed part of the lever, a. clamp se cured to the lower edge of the pane at the center thereof, a vertical lifting bar pivotally secured at its upper end to said clamp and at its lower end to the forward free end of the fulcrumed arm, a relatively short arm lixedly secured at one end to the fulcrumed end of the lever and extending rearwardlv therefrom at right angles thereto, a linlr pivotally connecting the outer end of the shorter arm to the fulcrumed end of the transversely extending arm, whereby the last menlll l lill l i tioned arm and the lifting bar will be actuated to operate the sliding window pane, a handle associated with the upper end of the uleruin lever and extending upwardly through the sill, said sill having formed with slot in which said handle is operable to facilitate the actuation oiA the 'ulormned lever, and counter-balancing means for 'holding the window pane andl the actuating means theretor in any adjusted position, said last mentioned means comprising a weivht slidable `vertically in the frame, a cable secured at one end to the weight and at its other end to the 'ree'end of the uleruined arm, and pulleys over which the cable is trained.
